A couple of years ago I wired up an LC-1 to my Trinity, and enjoyed logging wideband AFR with my other pids. Over time Trinity started to lose connection with the car more frequently, with the "data has halted - waiting for engine to start" message. I had assumed it was my OBD connector, but I've ...

Thanks Mike!

jrupert: If you can't get your hands on your old revision, do the calibration update, grab a new Stock Backup and send it to your tuner to have your tune updated with the new cal.

Id love to help you out, not sure why you have such animosity.

Help me out instead ... I'm not animalous.

My question is: If up update my calibration, will my "old" CMR tune (based on my old cal) still work?

If not, how can I return my Trinity back to 1r04? I can't see a download option for ...

For those who have a CMR tune, updating the Calibration would render our CMR tunes useless, right?

If that is correct, how can I return my Trinity to an older rev, like 1r04 ?

So I erased the custom tune from the Trinity in the hopes of grabbing a new 'stock backup' ... But I got the "This vehicle needs an update Download here: www.diablosport.com/dcx" message.

My question is: If up update my stock calibration, will my "old" CMR tune still work, or will I need to get a ...

I then went to marry my Trinity to the car, it already had my customer CMR tune and the latest software revisions loaded, and it's telling me it can not back up my original tune and gives me this message:

PCM: failed (0x00040600-0x00040e68)
expected: (0xa038)
calculated: (ox50a1)


Was this ever ...

Glad you posted this. I resolved this several months ago by doing what you did in the 2nd post -- essentially, have the LC-1 output 3v during warm up, then use the Trinity to view the sensor voltage. Plotted my min/max values according to the error and off I went.

I'd like to know too... specifically, can you still disable rear o2 sensors?

Well, apparently a shift light is in 1r04... So hopefully you didn't remove the text from the manual!

Cool stuff, thanks for the update. The shift light will be useful.

It's probably the nature of the beast, but it kinda sucks... Trinity owners get delayed updates, and we need to download a huge CROM and it takes several minutes to update the Trinity because the crom is so big....

Am I right in assuming we can't load up Predator croms in the Trinity, and Trinity users will always have to wait for updates compared to our Predator friends? An update was issued for 7135 and I'm anxiously awaiting it to be available for my Trinity.

If all this is true, is there an ETA on 1r04 ...

So this means we can't load up Predator croms in the Trinity, and Trinity users will always have to wait for updates compared to our Predator friends? An update was issued for 7135 and I'm anxiously awaiting it to be available for my Trinity.

I just got the Trinity, and I updated to the latest crom. I bench tested the 91+CAI tune and the 93+CAI tune. With 94 octane fuel in my car, both tunes yield absolutely no measurable gain. Actually, the 93+CAI tune is slightly slower.

I do have a Mopar CAI. I datalog during my tests, and I don't ...
